Outcomes of Prosthetic and Biological Grafts Compared to Arm Vein Grafts in Patients with Chronic Limb Threatening Ischemia

The optimal conduit for infrainguinal bypass (IIB) is single segment great saphenous vein (GSV). Unfortunately, GSV is not always available in patients with chronic limb threatening ischemia (CLTI). Other graft choices include arm vein grafts (AV), prosthetic grafts (PG) or biologic grafts (BG). Current data regarding the durability and limb salvage rates of those options is scarce, hence we aimed to investigate the impact of alternative graft types on post-operative and long-term outcomes on IIB in patients with CLTI.
